Check out VisaMapper, a handy site that answers the “do I need to do anything special to visit a certain place, and how, exactly, do I jump through the right hoops” questions you’ve got — and can minimize the embarrassment of heading home on the exact same plane you just spent 17hrs on to get to India or China (it happens every day). Plus, it lets you scoff at lesser countries (tell it you’ve got a Yemeni passport and watch as the world closes its doors).
